Referring more particularly to the drawings, the reference numeral 2indicates a shaft for supporting a rotatable object supporting member 4.In this instance the to of the surface 6. A sleeve is mounted on each ofthe surfaces 8 and since the sleeves are identical in strucings 16 and18 through its outer wall and rollers 20 and 22 are mounted in theopenings 16 and 18, respectively. The axis of each of the rollers 20 and22 is in a plane perpendicular to the axis of the rotatable member 4.The roller 20 extends into a longitudinally extending groove the sleeve10 cannot rotate The shaft of the roller 20 is preferably mounted ineccentric bushings 26 to provide for adjustment of the roll 20 radiallyof the member 4. Spaced apart circumferential rings 28 are secured tothe outer surface of the sleeve 10 in order to provide a space nieStates Patent 0 2,766,041 Patented Oct. 9, 1956 removed because thediameter of the sleeve at this point is less than the diameter ends.

tions and modifications may be made Without departing from the scope ofthe following claims.

I claim:

1. Apparatus for automatically centering moving elongated objectscomprising a rotatable object supporting structure, a sleeve slidablymounted on said structure at each side of its object supporting surface,means for positively causing said sleeves to rotate with the objectsupporting structure, a diametergreater than the diameter ofsaid objectsupporting surface adjacent thereto to provide a shoulder, .meansoperable when said structure is rotating for moving .said sleevesaxially, eluding apair of opposed rotatable ilobj'ect passes, the axes"intersecting at a point between the rolls and diverging "away from thedirection'of approach of the object, and

same direction and at the same angular velocity,

a fla ge on each of said sleeves having said object supporting structurein- 7 rolls over which the of rotation of said rolls underload saidrolls to rotate in the each of said shoulder tomeans for positivelycausing said rolls increasing in diameter from ward its inner end.

' 2 Apparatus for automatically centering a nioving elongated objectcomprising a rotatable object supporting structure, a'sleeve slidablyimounted on said structure at each side of .its object supportingsurface, a flange on each of ,saidsleeves having a diameter greater thanthe diameter ofsaid object supporting surface adjacent thereto toprovide a shoulder, each of said sleeves having a plurality of openingsthrough the wall thereof, a roller mounted in each of said openings withits axis in a plane perpendicular to the axis of said structure, saidrollers extending inwardly beyond the wall of said sleeve and bearing onthe said rotatable structure, said object supporting structure 25 havinga longitudinally extending groove in its outer sur- "when "said'structure is rotating positively causing slaid r o lls' face forreceiving one of said rollers, means operable i for moving said sleevesaxially, said object supporting structure including a pair of opposedrotatable rolls over which the object passes, the axes of rotation ofsaid rolls under load intersecting at a point between the rolls anddiverging away from the direction of approach 'of the object, and meansfor H to rotateinthe same direction and atthe same angular velocity,each of said 'rolls increasing in diameter from said shoulder toward itsinner end.
